Honda NSX (EU)

Coolant capacity & service interval

Honda NSX (EU) coolant capacity ranges from 12 to 16,5 liters. Service intervals consist of 40000 km or 48 months and 80000 km or 48 months. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Honda NSX (EU) 3.0 V6 24V carries an initial fill capacity of 16 to 16.5 liters, which reflects the total volume of the entire cooling system including the engine block, radiator, heater core, and all associated passages filled from a dry or fully drained state.
  • The service fill capacity of 12 liters is notably lower than the initial fill, indicating that a standard coolant drain does not evacuate the full system volume, leaving residual fluid in the block and other components.
  • Under normal use conditions, the coolant change interval is set at 40,000 km or 48 months, whichever comes first, with a service fill quantity of 12 liters applied at each interval.
  • A first change only condition extends the initial drain interval to 80,000 km or 48 months, also using the 12-liter service fill capacity, meaning the first coolant change is permitted at twice the distance of subsequent normal-use intervals.
  • The 48-month time limit applies equally to both the normal and first change only conditions, so calendar age alone can trigger a service event regardless of mileage accumulated.
